ESB project is created with this XML:
<jbossesb xmlns="http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/etc/schemas/xml/jbossesb-1.1.0.xsd" parameterReloadSecs="5">
needs to be created with this
<jbossesb xmlns="http://anonsvn.labs.jboss.com/labs/jbossesb/trunk/product/etc/schemas/xml/jbossesb-1.2.0.xsd" parameterReloadSecs="5">
Probably this is because JBDS 3.0 M4 only supports ESB 4.6 yet and SOA-P 5 is based on 4.7. The 4.6 version does not support the new http-gateway listener (see http_gateway quickstart)
Also (probably as expected), when I change to the jbossesb-1.2.0.xsd, the "tree" view of the jboss-esb.xml file editor does not work correctly.
